To all whom z't may concern:

Be it known that I, LOUIS KBssLER, a citizen of the United Statesresiding at Chicago, in the county of dook and State of Illinois, haveinvented certain new and useful Iinproven'uents in Filler-Tubes andClosures Therefoi' for Receptacles, of which the following is adescription.

My invention belongs to'that general class of devices known as fillertubes, and particularly vrelates to an improved tube and closure for thesame. The invention has among its objects the reduction of a device ofthe kind describe that is safe, simple, eiicient, durable, com act andsatisfactory for the purpose, whic may be used wherever foundapplicable. The invention has particularly among its objects theproduction` of a closure that may be used in connection with anysuitable form of Iiller tube or filling opening of a receptacle forclosing the opening where the tank is lilled, whereby excessive pressurein the tank may be re-- lieved, and Where as the contents of the tankare drawn off air may be admitted to fill the space formerly occupied bythe liquid. The creating of avacuum in the tank, and consequentimpairing of the discharge is pre-- vented, and at the saine time theescape of gas from the tank due t0 evaporation, 1s prevented. Otherobjects and advantages of the construction herein set forth will be0bvious to those skilled in the art from the disclosures herein 'veiL Tothis end my invention consists in the novel construction, arrangementand combination of parts herein shown and -described, and more in theclaims.

In the drawings, wherein like reference characters indicate like orcorresponding parts,

Fi re 1 is a sectional view taken substantially on line 1-1 of Fig. 3.`

Fig. 2 is a sectional View taken substantially on line 2-2 of Fig. 1;

Fig. 3 is a sectional View taken substantially on line 3 3 of Fig. 1

particularly pointed out` Fig. 4 is a sectional view taken substantiallyon line -l1 of Fig. 1, and

Fig. 5 is a sectional view taken substantially on line 5 5 of Fi 1.

Referring to the drawings, 1 is'a tube of suitable material providedwith an extending flange 2 at the upper end, formed integral therewith,if desired, the same being suitably formed in any desired manner forattachment to a tank 3, or the equivalent. The tube 1 is preferablyextended as at 2 above the flange 2, and is shown threaded at theexterior. Where'the tube is made for threaded engagement with .the tank,the Harige 2 may be formed similar to a nut, so as to plermit its beingengaged by a suitable wrenc when desired. The lower end of the tube isopen, and the same being covered with a lWire gauze 4:, which may bereinforced and protected by the coarser wire gauze 5, thereby preventingthe gauze 4 froml being easily fractured. The tube is also preferablformed with openings or apertures 6 t ereabout. near the bottom, whichare lcovered with wire gauze 7. I have shown a flanged collar S'arran edat the bottom, forming a convenient met od of securing the gauze partsto the tube, it being `understood that the same maybe soldered orotherwise securedn place. I also provide the tube with a series ofopenings or o ertures 9, arranged adjacent the to this Ieilig covered bygauze 10, secured'lie. placein any desired manner.

Arranged within tube 1 and spaced from, is an inner tube 11, which isformed with a iange 12 of a size to closely fit the inner wall or tube.1,- the same being ribbed as at 14eV if desired to provide spaces 13above the flange and aid 1n maintaining the parts in position. Theinner. tube in the preferred construction is of such length that theupper end 11 is adjacent the upper end 2 on the outer tube, and thepartition 12 is' heilig of any desired size and shape, and the bottom isclosed as at 16.

The closure for the tube consists of a neck part 18 arranged to besecured to the end of the outer tube, the same having one or moreopenings 19 through the same, and preferably recessed as at 20. Arrangedon the part 18 is aoap 21, the same being chambered as at 22, andarranged to sealt on the top 23 of part 18. As moet clearly shown inFig. 1, the part 21 is extended as at 24 to fit the recess `2.0, andinternally flanged as at 25. Projecting through the part 18 and the part21 isl a tubular stem 27, the saine being flanged as at 28 to overliethe flange 25. Arranged about the same is a spring 29, which bearsagainst pant 18 and the tubular part 39 carried by fthe tubularpirt 27,the

spring normally maintaining the cap. part 2.1

in the position shown in the drawings, so that the ange of .the part isseated on the top or seat 23 of part 18. As I have mentioned, part '27is tubular, the same having a chamber 30 communicating with the inletduct 31, fthe part being formed with a valve seat 32.

Arranged on the end of stem 27 is a cap 33, which is chambered andprovided with ducts 35, extending therefrom to the exterior, preferablyat the sides. Within the chamber 30 is arranged a valve 36, which isnormally maintained closed or against its seat 32, by the member 37 andspring 38, or equivalent means vfor the purpose. Part 39 is formed witha duct 40, the pant being shouldered 'so as to support the end of theSpring 38.

When it is desired to fill the tank to which the 'tube is applied, part18 is removed, carrying with :it the several parts described as iformingthe closure. The liquid may then be poured into the tank, from whencethe same passes through the openings 15 into the space between thetubes, and tluiough the wire ganzes 4, 5 and 7 to the interior of thetank. The air displaced within the tank passes through ythe wire gauze10 and openings-9, through the Spaces 13 between the tubes rte theexterior. Any dame is prevented rom ente-ring the tank by the gauze 4,5, 7 and 10, so that the tank cannot explode at the ller opening whilethe closure is removed for fill-.ing the tank, or when the closure isreplaced. In case of any pressure within the tank for any reasonwhatever the same will be relieved by the raising of .the part 21, Ithegas passing through the chamber out thiough the opening 19, and underthe cap between the same and ite seat. As the fuel is used up theforming of a vacuum within the tank is prevented by the admission of airthrough 'theopenings 35, duct 31, past the valve 36, through the chamber30,

als

11 into chamber 13, and through the openings 9. The valve 36 preventsthe escape of any fumes or gas from the interior of the tank. This isimportant, asin practically all garag the fumes from the fuel tank fillthe places, subjecting the same to possible fire and explosion. Ofcourse where the tubes shown are not employed, the closure may be usedin place of the ordinary cap, the lpressure in thetank being relieved orair admitted, etc., as described, but the tank, however, is notexplosion proof.

Having thus described my invention, it is obvious that variousimmaterial modifications may be made in the same Without depanting fromthe spirit of my invention; hence I do not wish to be understood aslim'- iting myself to the exaot form, construction, arrangement andcombination of parts herein shown and described, or uses mentioned.
